"It's actually very different when people self-select and create these spaces," Mark (above) says of friend lists. "And that's the social solution we're trying to go for."

“Download Your Data makes it so you can create and archive ZIP files of all of the stuff you’ve put on Facebook—all of your photos, videos, status updates, wall messages, profile information—so you can do whatever you want with it, and just download it all,” says Mark during the in-depth discussion.

“And that is pretty important because we, philosophically, believe that people own all that information. So they should be able to upload it and take it with them wherever they want.

“The Platform Apps Dashboard makes it so you can see how apps that you’re using are using your information. That should create more transparency around the type of info that apps are requesting and using, and should, hopefully, hold them accountable and make it so that they use as little of your information as possible—given now that what they use is gonna be visible,” adds Mark.

As for being inundated with the wrong types of friends, Mark explains that the new Groups feature should help by self-regulating things:

“This is really a social problem. When people talk about segmenting their lists, a lot people think that the right way to do that is just to give people an interface and they’ll create their own friends list.

“But it turns out that most people don’t want to do that. Maybe five percent of people want to do that. Then the next conclusion people come to is that, you should just have an algorithm that can do this for people. But algorithms just get it wrong a lot of the time.

“And even if they got exactly the group that you would create yourself, it’s different for you to arrive at it yourself. Maybe, like, your carpenter—the person you’re doing work on your house with—if they added you as a friend, you’d want to add them.

“But if someone just gave you an algorithm and said, ‘This person is your friend,’ you’d be like, No they’re not! What are you talking about? They’re my carpenter.”
